We found a bunch of letters from my grandfather to my grandmother before they got married, in late 1929 and early 1930s and he wrote on the back of the envelopes EVOL. The EVOL were not always together, they were sometimes on the corners of the flap. Any ideas what this might have stood for???
They lived in New York City at the time. He was born there and she is my grandma that came from Austria as a young child if that helps at all.
thanks.
